Skin Test For Allergy

What is a skin test for allergy?

This is a test done on the skin to identify the allergy substance (the allergen) that is the trigger for an allergic reaction.

How is an allergy skin test done?

A small amount of the suspected allergy-provoking substance (the allergen) is placed on the skin. The skin is then gently punctured through the small drop with a special sterile puncture device. An allergy skin test is also called a pric/puncture test. The older terminology was "scratch test."

What is a positive skin test?

If the skin reddens and, more importantly, if it swells, then the test is read as positive and allergy to that substance is considered probable.
